WALTER A. JONES, OF COLUMBUS, OHIO.

GLASS-DRAVI'NG APPARATUS.

To all whom it may concern Be it known that I, W'ALTER A. JoNEs,

residing at- Columbus, in the county of Franklin, State of Ohio, have invented certain new and useful Improvements in Glass-Drawing Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to glass drawing apparatus and particularly to melt-ing tanks having associated therewith exteriorly dis posed continuously supplied drawing or working pots. In apparatus of the type referred'to the drawing pot and the section of conduit disposed exteriorly of the tank, and

connecting said pot with the suppl of molten glass within the tank, frequent y become injured or broken so as to necessitate their replacement with similar perfect parts. When this condition arises it is necessary that the melting tank be closed down before it is possible to replace the damaged pot and conduit, which will result in loss of time, retardation of output and resultant financial loss.

It is therefore the object of this invention to so construct the drawing pot, associated conduit section, and pot kiln that they may all be moved bodily away from the melting tank'to permit of the replacement ofinjured parts without the necessit ofclosing down the melting tank and at ter such replacement of injured parts, may be returned with facility into operative relation to the melting tank.

With the above and other objects in view, the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully described and particularly pointed out in the appended claim.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters of reference denote'corresponding parts in the several views, and in which Figure 1 is a vertical section of a glass drawing apparatus constructed in accordance with the invention, Fig. '2, an inner end view of the drawing pot kiln with the conduit section formed integral with the pot shown locked in place by the removable wall section of the kiln, Fig. 3, a view simi Specification of Letters Patent.

Application filed January 20, 1912.

Patented Feb, 25,1913. Serial in. 672,349.

ng from the interior of the tank and :controlled by a'stopper'li-l. The outer end of the conduit 12 is provided with an annular flange 14 disposed entirely beyond the outer face of the side wall of the tank 10.

Radiating from the tank 10 are spaced rails 15 upon which is adapted to travel a wheeled drawing pot kiln A. This kiln comprises a bottom 16 having a drain open ing 17 and its inner face sloping from each side downwardlytoward the drain opening 17. The kiln A further includes an outer end wall 18 and a sectional inner end wall in cluding a fixed lower section 1!) and a removable upper section 20 supported upon the upper edge of said lower section 19. Rising from the bottom 16 are the usual side walls 21 and 22 which in conjunction with the outer end wall 18 and the upper section 20 ot' the inner end wall support the kiln roof 23 and this roof is adapted in turn to support a removable hood 2% which covers through an opening in the roof 23. The inner face of the bottom 16 of the kiln is provided on each side of the drain opening 17 with a plurality of grooves 25, the grooves on ,one side of the opening 17*corresponding in number and position to the grooves on the opposite side of said open-' ing. Supported upon the bottom 16 is a block 26 which is provided with a plurality of spaced transverse ribs 27 disposed on its lower side and seating respectively in the grooves 25. The ribs 27 are of greater depth than the grooves 23 so as to form passages 28 whereby molten glass disposed upon thel bottom of the kiln may pass freely beneath the block 26 to the drain opening 17. Supported upon the upper face of the block 26 is a drawing pot 29 which has formed integral therewith a conduit section 30 which extends through the sections 19 and 20 of the inner end walls of the kiln. The lower section 19 of the inner end wall of the kiln o with is provided with. a recess 3 which receives the lower portion of the conduit section 30, while the lower edge of the upper section 9.6 of the inner end Wall of the kiln is provided with a recess 32 Which receives the upper portion of the conduit section 3%) end of course mates With the recess 31. outer end of the conduit section 80 is provided with a reduced portion 33 adapted to intertit with the flange ll of the conduit 12 so as to aiiord uninterrupted communication between the interior of the tank 10 and the drawing pot 29.

By this construction it will be apparent that so long as the drawing pot 29 and conduit section are unimpaired the kiln A. may he maintained stationary upon the rails 15 in position to effect an interiitting connection between the conduit 12 and the conduit section 30. :ElOVv'QVQl', when the drawing pot '29 or the conduit section. 30 become injured or broken so as to render re placement necessary it is only essential that the stopper 13 be operated to close the conduit 153 and the kiln it moved along the tracks 15 away from the tank to a suitable. location. ,"ihen this 1s done the roof: 23 is first moved, and the section :20 of: the inner end Wall of the kiln detached. The pot and conduit section can then be removed. with facility from. the kiln and a new pot and conduit section supplied. After such replacement of parts the section 20 of the inner end Wall of the kiln is reapplied as is also the roof 23. lhe kiln is then moved on the rails 15 until the conduit section carried thereby is broughtinto interfitting re lation to the conduit section 12 Oil the tank 10 when the operation of the various parts may be again instituted by removing the stopper 13 from closing position with respect to the inlet of the conduit 12.

lVhat is claimed is:

In a glass drawing apparatus, a Wheeled pot liiln having a removable top and one side wall of which includes a fixed lower section and a reinoveble upper section, the adjacent edges of said fixed and removable sections being provided with mating recesses forming a passage, a pot mounted in said kiln, a supply conduit projecting laterally from the pot and communicating with the latter beneath its month, said conduit extending tl'irough the passage in said side Wall and locked against upward movement by said removable side wall section, said pot and conduit being thereby adapted for bodily removal from the kiln by the removal of said top and upper side Wall secu tion.

In testimony whereof. I aliix my signature, in presence of two Witnesses.
